 * public.css — layout for the PUBLIC marketing surface (#152 P1)
 * =============================================================================
 * Rules: every value is a design-system token (or a structural flex/grid
 * property with no themable value). Colors/sizes/spacing all resolve through
 * --ls-* so the app's dark block + any future redesign move this surface
 * automatically (PUBLIC_SURFACE_VISION.md §4). Loaded ONLY by
 * base_public.html — the app never links this file.
